The difficulties of establishing primary inductive culture and explant cultured browning in Camptotheca acuminata Decaisne in vitro became the barrier of cultural system. In this research, different parts of explant such as apical bud, lateral bud, seedling apical bud, seedling lateral bud, seed, and leaf were tested to discuss the effect of kinetin, cysteine, IBA, and leaf maturity on tissue culture. After 8 weeks culture, kinetin at high concentration 10 μM made serious browning on lateral bud and seedling lateral bud. Browning of apical bud were slighter than lateral bud, and apical bud sprouted at 100% induction rate of bud as soon as applied 2.5、5、10 μM kinetin. Better induction rate of bud sprout of seedling apical bud also can attain 75% at 2.5 μM kinetin treatment. No browning was observed in apical buds applied with cysteine treatment. Lower browning rate were observed in 25 mg•l-1 cysteine treatment of lateral bud, but a higher concentration at 100 mg•l-1 led to more serious browning and lower induction rate of bud sprout. Different explants were observed after 4 weeks cultured in 0, 1, 2, 3, 4 μM IBA. Adding IBA 3 μM can reduce browning rate of lateral bud to 11%, and made a higher induction rate of bud sprout at 78%. Seeds germination in IBA 2 μM treatment resulted in a higher germination rate of 90%. Leaf callus formation amount increased with IBA concentration. However, IBA 2 μM application formed green tight callus. In the culture of axillary bud and leaf, the CO2 concentration increased in the vessel at the beginning of dark period and decreased at the beginning of light period. In the culture of axillary bud, seed and leaf, applied higher IBA concentration treatment at 3、4 μM led to higher C2H4 concentration in the vessel. The leaves were divided by three maturities at S1, S2 and S3, which were induced to form callus. Only observed explant enlargement on the youngest stage(S1), which were induced with swollen tissue and bulges. The mature stage(S3) lead to serious browning. Better induction of compact callus were observed on S2 maturity.

In current years, extract of camptothecin from Camptotheca acuminata Decne have been used as anticancer medicine. The key point for plant material production were used clone to product Camptotheca acuminata Decne. by asexual propagation. In this research, we pursued the effect of plant growth regulators, and silver thiosulfate, STS on reduction improvement browning, sampling timing and light source on the explants growth of Camptotheca acuminata Decne. in vitro. In sampling timing, browning rate going up from spring to winter and survival rate gradually decrease. The highest survival rate is spring for 35%, browning rate just 1.4%. The highest browning rate is autumn for 28.2%, In the winter, explants almost of microbial contamination. The explants with 0.01 mg/L NAA and 0.5 mg/L BA for one month, and then 0.5 mg/L NAA and 0.5 mg/L BA or 0.5 mg/L IBA and 0.5 mg/L BA for one month. Explants has 0.8 cm between node with NAA, but only 0.4 cm with IBA. Explants with NAA seems to be weak. Explants with IBA are stronger. The aim of this study were inverstigated Light-Emitting Diode, LED, on Camptotheca acuminata Decne plantlet growth and development in vitro. Result indicated that under the white light had better length and width of leaf, it is 1.3 cm and 0.5 cm respectively. Under the blue light that leaf morphogenesis made more long and narrow, under combination light had better leaf area than under red light. In terms of chlorophyll a, b and total chlorophyll content that under the white and combination light showed more chlorophyll content than others light source on Camptotheca acuminata Decne plantlet. In terms of nutrient elements analysis that under the blue light showed higher content than others light source, excluded calcium and magnesium of Camptotheca acuminata Decne plantlet. Reserch of STS with no browning. Ethylene and carbon dioxide has been measure from 4 hours before darkness and 2 hours before photoperiod.

The happy tree (Camptotheca acuminate Decaisne) is one of the plants containing many alkloids, famous as camptothecin and 10-hydroxycamptothecin. An experiment of embryo in vito was conducted to induce callus from the happy tree. The results showed that the callus grew well under all MS medium treatments of 0.5 mg/l IBA + 4 mg/l BA, 0.5 mg/l picloram + 4 mg/l kinetin, 4 mg/l NAA + 2 mg/l BA, and 1 mg/l NAA, However, the callus obtained from the treatment of 4 mg/l NAA + 2 mg/l BA was soft and facilitated to be used as a material for the suspension culture experiment. In the multiple buds induce culture, the best result was obtained on the MS medium adding 0.5 mg/l IBA + 0.5 mg/l BA. The adventitious roots occurred best on the MS medium with 2 mg/l IBA in the culture. Four elicitor of salicylic acid, chitin, jasmonic acid and methyl jasmontate were selected to investigate 10-hydroxycamptothecin production from the happy tree using obtained callus suspension culture. The best productions of 10-hydroxycamptothecin were 887.5, 2579.5, 10246, 3836.6μg/g under the treatments of 100 μM salicylic acid, 3 ml/25ml chitin, 100 μM jasmocin acid and 200 μM methyl jasmonate, respectively, after a week incubation. Obviously, jasmonic acid has the best effect in inducing 10-hydroxycamptothecine production from the callus suspension culture.

Two processes of campothecin (CPT) extraction from fresh leaves of Camptotheca acuminate by alcohol and NaOH solution was developed and compared. The fresh leaves of C. acuminate were either extracted by 10 ml/g of 95% alcohol at 25℃ for 24 hours or extracted by 50 mM NaOH solution at 25℃ for 24 hours followed by adjusting pH value to 5.5 for another 24 hours. The extracts were then subjected to liquid – liquid extraction by uaing CH2Cl2 as extraction for the separation of CPT from other residues. Finally, a patition column filled with silica gel was used to further isolate CPT. In conclusions, if 1 g of C. acuminate leaves contained 1 mg of CPT, 0.54 mg CPT can be obtained with 69.95% purity from the alcohol extraction process while 0.49 mg of CPT with 75.39% purity would be obtained from the NaOH extraction process.
