n.三萜烯

Limonoids are a group of highly oxygenated,tetracyclic triterpene secondary metabolites derivatives. 檸檬苦素類似物是一類高度氧化的四環(huán)三萜類植物次生代謝物質(zhì)。

A slow-release matrix process ensures a full 10 hours of release, yielding 2 mg of triterpene glycosides. 一個(gè)緩慢釋放矩陣程序確保10個(gè)小時(shí)的充分釋放，收益率為2毫克的三萜甙。

Objective: To establish a method for HPLC fingerprint determination of the triterpene acids in Poria cocos. 目的:建立茯苓中三萜酸類成分HPLC指紋圖譜的測(cè)試方法。

Abstract Objective: To optimize the extraction process of the total triterpene of Centella asiatica from Centella asiatica (L.) Urb. 摘 要 目的：采用正交實(shí)驗(yàn)優(yōu)化從積雪草中提取積雪草總苷的工藝。

The sterols, triterpene alcohols and 4-methylsterols from the unsaponifiables in safflower seed oil were separated and analysed by HPLC, GLC and GS-MS. 采用高效液相色譜、氣相色譜及氣-質(zhì)聯(lián)用方法分離和測(cè)試紅花籽油不皂化物成分，結(jié)果表明，紅花籽油不皂化物主要成分為甾醇、三萜醇和4-甲基甾醇等。
